SOFIA/EXES observations of water absorption in the protostar AFGL 2591 at high spectral resolution

We present high spectral resolution (similar to 3 km s(-1)) observations of the nu(2) ro-vibrational band of H2O in the 6.086-6.135 mu m range toward the massive protostar AFGL 2591 using the Echelon-Cross-Echelle Spectrograph (EXES) on the Stratospheric Observatory for Infrared Astronomy (SOFIA). Ten absorption features are detected in total, with seven caused by transitions in the nu(2) band of

Nursing students' experiences of assessment by the Swedish National Clinical Final Examination.

The Swedish National Clinical Final Examination (NCFE) was established in 2007 in order to examine nursing students' clinical competence upon completing their Bachelor's degree in nursing. The NCFE constitutes an innovative method of examination, divided into two parts: a written and bedside test. The aim of this study was to evaluate nursing students' experiences of being assessed by means of the

The Multiple Silicone Tube Device, "Tubes within a Tube," for Multiplication in Nerve Reconstruction.

Multiple nerve branches were created during the regeneration procedure after a nerve injury and such multiple branches are suggested to be used to control, for example, prosthesis with many degrees of freedom. Transected rat sciatic nerve stumps were inserted into a nine mm long silicone tube, which contained four, five mm long, smaller tubes, thus leaving a five mm gap for regenerating nerve fibe

Researching Governance for Sustainable Development: Some Conceptual Clarifications

This article addresses two problems characterizing policy thinking on environmental change and sustainable development. First, the role of the social sciences in the wider processes of governance is sometimes misrepresented such that the likelihood of achieving consensual decision-making on environmental phenomena is overestimated. Second, the social science discourse on governance is plagued by c

Parameter-Uniform finite element method for two-parameter singularly perturbed parabolic reaction-diffusion problems

In this paper, parameter-uniform numerical methods for a class of singularly perturbed one-dimensional parabolic reaction-diffusion problems with two small parameters on a rectangular domain are studied. Parameter-explicit theoretical bounds on the derivatives of the solutions are derived. The method comprises a standard implicit finite difference scheme to discretize in temporal direction on a un

Long-term survival in young and middle-aged Hodgkin lymphoma patients in Sweden 1992-2009 - trends in cure proportions by clinical characteristics.

Trends in Hodgkin lymphoma (HL) survival among patients treated outside of clinical trials provide real-world benchmark estimates of prognosis and help identify patient subgroups for targeted trials. In a Swedish population-based cohort of 1947 HL patients diagnosed 1992-2009 at ages 18-59 years, we estimated relative survival (RS), cure proportions (CP) and median survival times using flexible pa

Family perspectives in lynch syndrome becoming a family at risk, patterns of communication and influence on relations

Background: A growing number of individuals are diagnosed with hereditary cancer. Though increased levels of anxiety and depression have been demonstrated around the time of genetic counselling, most individuals handle life at increased risk well. Data have, however, been collected on individual basis, which led us to focus on family perspectives of hereditary cancer. Methods: Lynch syndrome repre

Frequency-dependent variation in the two-dimensional beam pattern of an echolocating dolphin.

Recent recordings of dolphin echolocation using a dense array of hydrophones suggest that the echolocation beam is dynamic and can at times consist of a single dominant peak, while at other times it consists of forward projected primary and secondary peaks with similar energy, partially overlapping in space and frequency bandwidth. The spatial separation of the peaks provides an area in front of t

Vulnerability versus resilience to prenatal stress in male and female rats; Implications from gene expression profiles in the hippocampus and frontal cortex

Adverse life events during pregnancy may impact upon the developing fetus, predisposing prenatally stressed offspring to the development of psychopathology. In the present study, we examined the effects of prenatal restraint stress (PS) on anxiety- and depression-related behavior in both male and female adult Sprague-Dawley rats. In addition, gene expression profiles within the hippocampus and fro

Mutations in TERT promoter and FGFR3 and telomere length in bladder cancer

Mutations in the promoter of the telomerase reverse transcriptase (TERT) and fibroblast growth factor receptor 3 (FGFR3) genes constitute the most recurrent somatic alterations in urothelial carcinoma of bladder. In this study, we screened DNA from 327 urothelial bladder carcinomas from well-documented patients, with different stages and grades and known TERT promoter mutational status, for FGFR3

Implicit Euler and Lie splitting discretizations of nonlinear parabolic equations with delay

A convergence analysis is presented for the implicit Euler and Lie splitting schemes when applied to nonlinear parabolic equations with delay. More precisely, we consider a vector field which is the sum of an unbounded dissipative operator and a delay term, where both point delays and distributed delays fit into the framework. Such equations are frequently encountered, e.g. in population dynamics. T

Novel coagulation factor concentrates: Issues relating to their clinical implementation and pharmacokinetic assessment for optimal prophylaxis in haemophilia patients.

Prophylaxis is considered the optimal treatment regimen for patients with severe haemophilia, and may be especially important in the prevention of joint disease. Novel coagulation factor concentrates with prolonged half-lives promise to improve patient treatment by enabling prophylaxis with less frequent dosing. With the call to individualize therapy in haemophilia, there is growing awareness of t

Gas-borne particles with tunable and highly controlled characteristics.

Abstract For nanotoxicology investigations of air-borne particles to provide relevant results it is ever so important that the particle exposure of, for example cells, closely resembles the "real" exposure situation, that the dosimetry is well defined, and that the characteristics of the deposited nanoparticles are known in detail. By synthesizing the particles in the gas-phase and directly deposi

Distribution pattern of the Ki67 labelling index in breast cancer and its implications for choosing cut-off values.

The Ki67 labelling index (LI - proportion of staining cells) is widely used to reflect proliferation in breast carcinomas. Several cut-off values have been suggested to distinguish between tumours with low and high proliferative activity. The aim of the current study was to evaluate the distribution of Ki67 LIs in breast carcinomas diagnosed at different institutions by different pathologists usin

Development and evaluation of methods for starch dissolution using asymmetrical flow field-flow fractionation. Part I: Dissolution of amylopectin.

We have investigated methods of starch dissolution with the aim of finding an optimum method to completely dissolve starch granules to form a molecularly dissolved starch solution without degradation of the polymers. Glycogen was used as a model molecule for amylopectin, to identify the dissolution conditions under which the degradation of the polymers was limited or not present. Dissolution was p

Fisher information analysis in electrical impedance tomography

This paper provides a quantitative analysis of the optimal accuracy and resolution in electrical impedance tomography (EIT) based on the Cramér–Rao lower bound. The imaging problem is characterized by the forward operator and its Jacobian. The Fisher information operator is defined for a deterministic parameter in a real Hilbert space and a stochastic measurement in a finite-dimensional complex Hi

mTOR Inhibition Alleviates L-DOPA-Induced Dyskinesia in Parkinsonian Rats

The development of dyskinesia upon chronic L-DOPA treatment is a major complication for the management of the motor symptoms in Parkinson's disease (PD) patients. Efforts are made to understand the underlying mechanisms and identify targets for the pharmacological alleviation of dyskinesia without affecting the therapeutic effect of L-DOPA. Previous studies have shown that the mTOR pathway is hype

Routinising research : academic skills in analogue and digitial worlds

This paper explores research routines which are so mundane that they are rarely noticed and may be hard to even verbalise. How does one acquire the bodily dexterity of rifling through a filing cabinet, skimming Google lists, or judging a book by holding in it one’s hands? Drawing on interviews with and observations among scholars of both the analogue and digital generations, mainly in the social a

The silkmoth cocoon as humidity trap and waterproof barrier

To better understand how silkmoth cocoons maintain the correct internal moisture levels for successful pupation, we examined cocoons from the long-domesticated mulberry silkmoth Bombyx mori as well as from two wild silkmoth species, Antheraea pernyi and Philosamia cynthia ricini. We determined fluid-independent values for the porosity, tortuosity and permeability of the inner and outer surfaces of
